Are these things I should consider bad

Did you move the scope probe ground lead during taking this series?
[Edit: you should connect the ground lead of the probe you are using to the chassis, keep it attached at one particular point for all the measurements, and do not connect any other scope ground leads to the chassis.]

The "fat" traces could be superimposed 60 Hz hum due to intermittent probe ground (can't tell from stills, but you could verify by slowing the scope sweep to vertical rate).

In any case, there appears to be ripple on the green cathode and grid, less on red and blue. Why they should be so different doesn't make a huge amount of sense, unless it varies with the scope probe grounding, because the bars you have shown pictures of appear to be monochrome - so they should be in all three guns.

Also, in the off-screen shots with a regular picture, the bars aren't visible. Are they visible to the eye at all with a regular picture, or only with a plain black scene?
